초록 ▼

Passive water management techniques are provided in an air-breathing direct oxidation fuel cell system. A highly hydrophobic component with sub-micrometer wide pores is laminated to the catalyzed membrane electrolyte on the cathode side. This component blocks liquid water from traveling out of the cathode and instead causes the water to be driven through the polymer membrane electrolyte to the cell anode. The air-breathing direct oxidation fuel cell also includes a layer of cathode backing and additional cathode filter components on an exterior aspect of the cell cathode which lessen the water vapor escape rate from the cell cathode. The combination of the well laminated hydrophobic microporous layer, the thicker backing and the added filter layer, together defines a cathode structure of unique water management capacity, that enables to operate a DMFC with direct, controlled rate supply of neat (100%) methanol, without the need for any external supply or pumping of water. The cell anode is provided with a hydrophilic backing layer. When the water is driven through the polymer membrane electrolyte from the cell cathode to the cell anode chamber, it is available for the anodic reaction, and any excess water is carried out along CO2 ventilation channels to the outside environment.

What is claimed is: 1. A membrane electrode assembly for use in an associated direct oxidation fuel cell, comprising: (A) a protonically conductive, electronically non-conductive membrane electrolyte, having an anode aspect and a cathode aspect; (B) an anode catalyst disposed in contact with said anode aspect of the protonically conductive, electronically non-conductive membrane electrolyte; (C) a cathode catalyst that is suitable for oxygen electro-reduction reactions being disposed in contact with said cathode aspect of the protonically conductive, electronically non-conductive membrane electrolyte; (D) a microporous layer located between the cathode catalyst and a cathode backing layer, wherein the microporous layer blocks liquid water that is generated on the cathode aspect from migrating out through the cathode backing layer and forces the liquid water to travel across the protonically-conductive membrane to the anode catalyst for complete anodic oxidation, without any external supply or external redirection of the water, wherein the microporous layer comprises a layer of expanded PTFE facilitating cathode liquid water blocking; (E) an anode diffusion layer that is in contact with the anode catalyst on the membrane electrolyte; and (F) a fuel supply comprising neat methanol. 2. The membrane electrode assembly of claim 1, wherein when operated with the neat methanol supply to the anode diffusion layer at a rate of approximately 100% of a design cell current, at least 80% of the methanol is converted to CO2 at a cell voltage above 0.3V. 3. The membrane electrode assembly of claim 1, wherein the microporous layer has a PTFE weight percentage of greater than or equal to 50%. 4. The membrane electrode assembly of claim 1, wherein the microporous layer comprises micropores that are of a pore diameter between about 1.0 and 0.1 μm in order to block the liquid water. 5. The membrane electrode assembly of claim 1, wherein the microporous layer comprises a layer formed by coating and bonding carbon particles together with polyfluorocarbon compounds.
